Question 35

immune system

Answer 35

the bodys defense against disease

Question 36

how the immune system works

Answer 36

1- every pathogen has a different shaped antigen on its surface 2- once the pathogen enters a human body, the body sends out proteins called antibodies 3- antibodies that have a similar shape to the antigen will attach to the pathogen 4- white blood cells will then engulf the pathogen and destroy it

Question 37

vaccine

Answer 37

the use of a weakend or dead pathogen to induce an immune response

Question 38

how a vaccine works

Answer 38

1- get injected with a dead or weakend virus or pathogen 2- reacts to the antigen8uiu987 3- body creates antibodies against that pathogen 4- antibodies attack the vaccine particles

Question 39

how a vaccine works

Answer 39

1- get injected with a dead or weakend virus or pathogen 2- reacts to the antigen8uiu987 3- body creates antibodies against that pathogen 4- antibodies attack the vaccine particles

an immune response to a usually harmless substance

Question 41

aids

Answer 41

a viral disease that attacks the immune system us now open to other infections such as pnuemonia that can cause death

Question 42

antibody

Answer 42

a protein found in the blood that is produces in response to a specific antigen

Question 43

antigen
